Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499652, here are decompositions:

31 + 31499621 = 31499652
53 + 31499599 = 31499652
59 + 31499593 = 31499652
193 + 31499459 = 31499652
241 + 31499411 = 31499652
251 + 31499401 = 31499652
269 + 31499383 = 31499652
281 + 31499371 = 31499652

Showing the first eight; more decompositions exist.
